Item A new fungicide to control black stripe disease of rubber (Hevea brasiliensis)(Rubber Research Institute. Agalawatta, 1986) Liyanage, N.I.S.; Warnapura, S.S.; Fernando, B.A new fungicide code No. San 374 F4 PA09 significantly controlled the spread of black stripe disease on four Hevea clones, artificially inculated with Phytophthora meadii. The same fungicide caused a decrease in the number of depression on the bark in naturally infected trees, although the length of depressions were not reduced. The number of lesions formed owas less after the application of San 374 F4 PA09 compared with all other fungicides tested.Item Some effects of isolates of Trichoderma on Rigidipourus lignosus(Rubber Research Institute. Agalawatta, 1991) Wijesundara, R.L.C.; Jeyanathan, S.; Liyanage, N.I.S.Seven forms of Tricoderma were isolated from soil obtained from rubber plantations. All the isolates secreted compounds inhibitory to the growth of Rigidiporus lignosus the causal agent of the white root disease of rubber. Further, the Trichoderma isolates interacted with the hypase of R. lignosus, the interaction resulting in harmfull effects on R. lignosus hyphae. Of the isolates examined T. Koningii isolate IV and T. harzianum appear to be very promising as potential biocontrol agents
